      Hello 👋

      For the context I have a SG-1100 (version 23.09.01 PLUS) and a SG-3100 (same version). Both have the recent KEA DHCP backend for IPv4 and IPv6. My dhcp6 config is a bit special because it contains a lot of raw-options and advanced options because I need to authenticate to my ISP.

      I have no idea if the issue occurs on the kea-dhcp6 package or the client dhcp6c. When I boot my netgate appliances, there is no IPv6 address for the WAN interface and my clients can't get a global IPv6 since the RADVD is down.

      When this issue occurs I need to manually go the interfaces > WAN settings, press Save (even if I didn't change any settings) and reload the interface. Then boom I get an IPv6 ! All my settings are working fine but its just not working at boot only.

      Here the DHCP logs right after the boot :

      Do you have ideas why this issue occurs ? I would like to get my prefix at boot so my clients get an IPv6. Im rebooting my appliances quite often so for me its not a good workaround to go everyday in the interfaces settings to reload the settings.

      Thanks for your help !

        The KEA logs "Here the DHCP logs right after the boot :" I see only the server isde of things.

        A you can see clearly in the "And after I reload the interfaces :" : it's dhcp6c (not kea process probably) and this is the DHCP6Client, which should kick in when the WAN comes active.
        Also during boot.

        @Superpaul209 said in KEA DHCP6 doesn't start/get a prefix at boot:

        I need to authenticate to my ISP.

        Like I've see people doing here in France, ISP Orange.

        @Superpaul209 said in KEA DHCP6 doesn't start/get a prefix at boot:

        When this issue occurs I need to manually go the interfaces > WAN settings, press Save (even if I didn't change any settings) and reload the interface.

        The next time, right after a reboot, before you do the "Save", can you check if dhcp6c was fired up ?

        Is this your setup :

          @Gertjan You are right, I think the problem comes from the dhcp6 client which doesn't start during boot. You don't see it in the logs because there aren't any logs of it. It only comes up when I reload the interface.

          Also yes im living in France, it requires to put raw options and a specific config for Orange ISP :

            Ok, yes, I've seen the DHCP Option generators.

            Strange that the dhcp6c doesn't start at boot.
            "It should".

            My pfSense 23.09.1 and 24.03-Beta since a week or so, is playing nicely, but I'm still using the LB6 as the upstream ISP router. I gets the "one" (just one /64) prefix out of the box.

            I didn't find a reason to reboot my 4100, I leave it running all the time. I can't compain about my fibre connection, it can stay up for weeks if not months.

            My dhcp6c wakes up every 5 minutes or so, and does 'its thing' :

            0232ca20-7782-4e52-b1b2-9f2aa0bc12fb-image.png

            Btw : I'm not using the kea stuff right now, as I need to use DHCP options on the LAN=server side (some captive portal testing is going on, as I use my hotel clients as guinea pigs ^^ )

              @Gertjan or anyone else

              Is there a command to reinstall the dhcp6c package (only the client) to the default one in PfSense Repository ? It could potentially be a corruption issue or an update issue on my package which makes it no work at boot.

              I don't find other reasons why it doesnt start at boot. There aren't debug logs.

                If the file ( /usr/local/sbin/dhcp6c ), an executable, was corrupted, then you would see for sure logs mentioning this.

                Because I have this :

                67a900f4-63db-40cf-a348-47d81afd78f6-image.png

                Check :

                Again : I'm using ISC, not KEA !

                  My router is up since this morning, there is only the DHCP6 KEA backend running and no dhcp6c

                  79657 root 20 0 39M 22M select 0 0:02 0,00% /usr/local/sbin/kea-dhcp6 -c /usr/local/etc/kea/kea-dhcp6.conf{kea-dhcp6}

                  a497d35b-e99c-40c5-a321-63ab889ee9d5-image.png

                  Then when I reload the WAN interface, it shows up.

                  25699 root 55 0 13M 2544K select 1 0:00 0,00% /usr/local/sbin/dhcp6c -D -n -c /var/etc/dhcp6c.conf -p /var/run/dhcp6c.pid mvneta0.832

                      @Gertjan I think the issue occurs because im using a "custom" dhcp6c package but this shouldn't be a problem for the client boot.
                      ad865a17-2bec-4d73-be20-55a0bb27cfbc-image.png

                      Its a compiled dhcp6c package to have new features like raw-options compatibility and ISP requirements. Its used in the OpnSense project.

                      e888f7a4-6d45-49e1-960b-5b474e8b7a53-image.png

                      There is a redmine ticket opened since 6 years with no answer : https://redmine.pfsense.org/issues/8173

                      I had injected the new file into /usr/local/sbin and replaced it with the old version.

                      Anyway, the custom package is working so thats not the issue but its more about the automatic start at the boot. Is there a file/parameter which automatically starts packages like other linux dists ?

                        Here : /usr/local/etc/rc.d/dhcp6c

                        You are using 23.09.1 : what is the kernel version ? 14 ?
                        What is the kernel version against which your dhcp6c is compiled ? etc etc .

                          The latest pfSense version uses the kernel 14 of FreeBSD.

                          About the compiled "custom" executable :
                          /usr/local/sbin/dhcp6c: ELF 64-bit LSB shared object, ARM aarch64, version 1 (FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, for FreeBSD 12.1, FreeBSD-style, stripped

                          And here is the content of the file /usr/local/etc/rc.d/dhcp6c

                          #!/bin/sh

# PROVIDE: dhcp6c
# REQUIRE: netif
# BEFORE: NETWORKING
# KEYWORD: shutdown

                            Isn't that asking for troubles, using a kernel 12.1 binary 'dhcp6c' on a version 14 system ??

                            /usr/local/etc/rc.d/dhcp6c : I've the same file, I guess. I left 23.09.1 several weeks ago, using 24.03-RC now.

                            No "help me" PM's please. Use the forum, the community will thank you.
                            Edit : and where are the logs ??

                              I will need to compile it again on the new kernel version 14 or 15. I don't that would change anything but I guess I will have to try.

                              About the dhcp6c config /usr/local/etc/rc.d/dhcp6c, is it NO by default for you ?

                              : ${dhcp6c_enable="NO"}

                              Is it the automatic start at boot or something else ?

                                @Superpaul209 said in KEA DHCP6 doesn't start/get a prefix at boot:

                                dhcp6c_enable

                                I don't think this 'auto start' script is used by pfSense.
                                It's there s it is part of the standard framework when the dhcp6c package was included into pfSense.
                                Example : it locates the config (dhcp6c.conf) in the default FreeBSD location, not the one used by pfSense.

                                The dhcp6c process is fully controlled from /etc/invc/interfaces.inc :

                                See here, where it is started : https://github.com/pfsense/pfsense/blob/88670c6c167418e7d12b010c0ce8b7d06c2b757f/src/etc/inc/interfaces.inc#L3848 line 3864 with the correct paths (in /var/...).

                                  @Gertjan Hello again, im back after 15 days because I needed to recompile everything with the latest FreeBSD kernel. So everything is now compatible for FreeBSD 15.0 (which is the kernel of pfSense).

                                  The new file reports as :

                                  /usr/local/sbin/dhcp6c: ELF 64-bit LSB executable, ARM aarch64, version 1 (FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, for FreeBSD 15.0 (1500012), FreeBSD-style, stripped

                                  You can see how I have done the steps to compile it here : https://github.com/Superpaul209/dhcp6c-armv7
                                  Everything is up to date and you can find the binaries on this GitHub for arm64 and armv7 (for those who would like them if they are living in France).

                                  The installation was successful on each pfSense, after a reboot Im now having an IPv6 ! The problem was therefore one of compatibility with the kernel version which was too old.

                                  Thanks for your ideas and your help, it has solved my issue 😊
